Figure 1.

Comparison of promoters following lentivirus injection in rat brain. Lentiviruses
were stereotaxically injected into rat hippocampus and examined after three months.
A. eGFP expression driven by the ubiquitin-C promoter (Ubi-C) was consistently superior
to that of other promoters, including the platelet-derived growth factor promoter
(PDGF) and cytomegalovirus. Lower panels show representative higher power images of
eGFP driven by Ubi-C- (B), cytomegalovirus- (C), and PDGF- (D) promoters in lentivirus/eGFP-injected rats.
